986 (obj_elf_size): Deleted unused code. If size is non-reducible
987 expression, allocate some storage for the sy_obj field and copy
989 (elf_frob_symbol): New function. Computes sizes, calls
990 ecoff_frob_symbol if appropriate.
992 * write.c (fixup_segment): For i386 elf and coff (for now), don't
993 add in value of symbol from another defined section of the file.

1052 Add a space after "pc-relative" in the error message.
1053 (tc_i386_fix_adjustable) [BFD_ASSEMBLER]: Reject
1054 BFD_RELOC_386_GOTOFF relocs.

1096 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1098 * configure.in: Set bfd_gas for all sparc targets in one place,
1099 instead of separately for each. Correctly handle user-supplied
1100 "--enable-bfd-gas" option.
1102 * gdbinit.in: Move "break abort" to end, in case gdb complains.
1104 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:

1112 (indent_level): No longer static.
1113 (print_symbol_value_1): Don't print frag address if it matches

1117 (print_expr_1): Fix whitespace before printing X_add_number.
1119 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
1120 not symbol_new, for symbols holding expression values.
1121 * expr.h (make_expr_symbol): Move declaration here.
1122 * write.c (fix_new_exp): Handle O_add by creating an
1123 expression-valued symbol, and calling fix_new_exp recursively.
1124 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
1125 undefined symbol and a constant, fold the constant into the fixup,
1126 and refer to the undefined symbol directly. Then process the
1127 fixup again from scratch.
1128 (write_object_file): Before calling adjust_reloc_syms, make a pass
1129 through the symbol list trying to resolve values.
1131 * write.c (print_fixup): New routine, for debugging.
1132 (write_relocs): Call bfd_install_relocation. Deleted various
1133 hacks for working around problems with bfd_perform_relocation.
1135 * Makefile.in (VERSION): Update to 2.4.90.
1137 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

1150 * write.c (write_relocs): Add file name and line number to
1151 as_fatal calls. Handle bfd_reloc_overflow case specifically when
1152 RELOC_EXPANSION_POSSIBLE.
1154 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
1156 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
1157 here. Use them for deciding which PRINTF*LIKE macro definitions

1160 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
1161 default definitions matching what we were doing before.
1162 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
1163 always use the varargs form if not using stdarg. It's safe to
1164 always use vfprintf, because libiberty will provide it if the
1165 native system doesn't. Also, always make format be const.
1166 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.

1181 (listing_newline): Check filename as well as line number when
1182 deciding whether to record it.
1183 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
1184 false (if defined) as well as checking for reg_section.
1185 (listing_listing): Iterate fetching lines while line number is too
1186 low, and we haven't run off the end of the input file.
1188 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
1190 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)
1192 * ecoff.c (ecoff_generate_asm_lineno): check if

1199 * config/ho-*.h: Now-unused files deleted.
1201 * symbols.c (copy_symbol_attributes): New function. Copies BFD
1202 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
1203 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
1204 zero. Don't call obj_frob_forward_symbol.
1205 * read.c (pseudo_set): Call copy_symbol_attributes, but only if
1206 X_add_number is zero.
1207 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
1209 * config/tc-i960.c: Lots of whitespace, comment reformatting,
1211 (strchr): Don't declare.

1213 md_estimate_size_before_relax, md_ri_to_chars,
1214 md_create_short_jump, md_create_long_jump.
1215 (brtab_emit): Use data_section, not SEG_DATA.
1217 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1219 * config/vms-conf.h: new file, manually derived from conf.in.
1220 * config-gas.com: use it, and eliminate obsolete "host.h".

1230 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
1231 from the csect of the enclosing block.
1233 * config/tc-mips.c (insns_since_cache_access): Remove.
1234 (append_insn): Remove setting of insns_since_cache_access, and
1235 special 4600 handling; it turns out not to be required.
1237 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1239 * config/tc-mips.c (md_shortopts): Remove E.
1240 (md_longopts): Add EB and EL.
1241 (md_parse_option): Handle -EB and -EL as separate options, rather
1242 than as a single -E option with an argument.

1251 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
1253 * configure.in: Test for remove, not delete. Fix cross-assembler
1255 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
1258 * read.c (pseudo_set, case O_symbol): If
1259 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
1260 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
1261 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.

1265 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
1266 many others): new macros; values obtained from "DSTRECRDS.SDL".
1267 * config/obj-vms.h (various): use them.
1268 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
1269 representation (only enum bitfields can avoid being bitstrings).
1270 (bitfield_suffix, setup_basic_type): new routines.
1271 (VMS_typedef_parse): use them. Now recognize bitfields of all
1272 integral types, not just type `int'. Caveat: the representation
1273 used for bitfields still does not work for objects placed in
1274 registers, and gcc's optimizer sometimes puts small structs there.
1276 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
1278 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
1279 bit from const_flag.
1280 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
1281 (tc_frob_label): define this to call vms_check_for_special_label,
1282 and declare the latter.
1283 * config/obj-vms.c (vax_g_doubles): declare this file-scope
1285 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
1286 (vms_check_for_special_label): new routine (tc_frob_label).
1287 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
1288 and `gcc2_compiled.' labels; they won't reach here any more.
1289 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
1290 double', use `vax_g_doubles' flag to select type of double.
1291 (VMS_write_object_file) [traceback setup]: don't pass symbols
1292 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
1293 and TBT_Routine_End functions.

1297 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
1298 S_GET_VALUE() to avoid many repeated function calls.
1299 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
1300 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
1301 gets requested. [All the HACK_DEC_C_STARTUP code appears to
1302 be obsolete; gcc does it automatically for vms target. It's
1303 also misnamed, because it is for the "VAX C" run-time library,
1304 not the newer "DEC C" one which has much different startup code.]
1305 {various}: use `S_SET_xxx(symbol,new_value)' rather than
1306 `S_GET_xxx(symbol) = new_value'.
1308 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1310 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
1311 not &bfd_abs_section.
1313 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1315 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
1317 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
1319 * expr.c (expr): Don't reduce the difference of two symbols in the
1320 same frag if the symbols are not in normal sections.
1322 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
1323 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
1324 (obj_attach_unwind_info): Do not define. Not needed anymore.
1325 * config/tc-hppa.c: Delete whitespace at EOL.
1326 (struct hppa_fix_struct): Delete fx_unwind field and all references.
1327 (fix_new_hppa): Last arg is now a pointer to an int. Do not
1328 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
1329 fixups, store 32bits of unwind information in the fx_addnumber
1331 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
1332 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
1333 pointer to 32 bits of unwind info.
1334 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
1335 pointer to the dummy symbol; set the addend field to fx_addnumber.
1336 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
1337 rather than &bfd_XXX_section.
1339 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1341 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
1342 value by one; discard adjustments previously being made. From
1345 VMS- and Vax-related changes from Pat Rankin:
1346 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
1347 * vmsconf.sh: no longer have make-gas.com echo text about needing
1348 to modify the gcc-vms driver when intending to use with gcc 1.x.
1349 * as.c (parse_options): suppress 'v' from std_short_options and
1350 eliminate VMS-specific conditional initialization;
1351 [default case]: check for '-v' if md_parse_options doesn't recognize

1355 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
1356 for O_big literal operands (double floats and long long ints);
1357 [VMS, md_shortopts]: add second colon after 'v';
1358 (md_parse_options) [VMS, case 'v']: check for argument, so
1359 caller can handle `-v' w/o arg.

1363 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
1364 is defined, put the tx_offset into the r_offset.

1399 * as.c: ...from here.
1400 (parse_args): Use them always.
1401 (main): Use exit rather than return.
1403 * Makefile.in (*_FOR_TARGET, INSTALL_XFORM, install, uninstall):
1404 Rewrite handling of program_transform_name.
1406 * configure.in: Test for functions unlink and delete.
1407 * as.h: If unlink isn't available but delete is, define unlink to

1412 * .gdbinit: Deleted.
1413 * aclocal.m4 (GAS_GDBINIT): Deleted.

1417 to ensure that older versions of autoconf aren't used.
1418 * Makefile.in: Added @configure_input@ line.
1419 (configure): Deleted rule.
1421 Tue Sep 13 12:08:20 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
1423 * config/obj-coff.c (fixup_segment): After handling the difference
1424 of two symbols from the same segment, set fx_subsy to NULL, to

2484 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
2485 for gcc2's predefined types "long double" (same as double, as

2492 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
2493 of 0, because the latter indicates success rather than failure

2732 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,

2852 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
2854 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
2856 * vmsconf.sh: In generated file, get ".obj" suffix right, build
2857 source files from other directories into objects in the current
2858 directory, and specify PSECT attributes explicitly to linker.
2859 Also added missing label.
2860 * Makefile.in (stamp-mk.com): Reference new variable

2878 argument, the reloc type.
2879 (load_register): Pass reloc type to macro_build for 'u'.
2880 (macro): Likewise. For M_LA_AB permit a difference expression
2881 when generating embedded PIC code between an arbitrary symbol and
2882 a symbol in the .text section.
2883 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and

2892 * subsegs.c (subsegs_begin): Call memset with args in the correct
2894 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2895 to NULL instead of 0.

2924 (hppa_tc_symbol): Likewise.
2926 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2927 elf_tc_make_sections stuff. It was there to support PA braindamage
2928 which has been fixed, and in the case of elf_tc_make_sections is
2929 redundant with elf_tc_final_processing.
2931 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2933 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2949 don't spew remainder of input file in error message.
2950 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2951 message with reloc type and try to process remainder of file.
2953 * doc/Makefile.in (install-info-as, install-info-gasp): New
2954 targets, now explicitly checking $(srcdir) for info files.
2955 (install-info): Depend on both of them; do nothing more.

2959 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2961 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2963 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2964 flag rather than signedp field. Only permit extended range if
2965 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2966 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2968 * config/tc-ppc.c (ppc_size): New static variable.
2969 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2970 (md_begin): If an instruction has a size specific flag set, only
2971 add it if we are assembling that size.
2973 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2975 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2976 cross section PC relative relocs right for COFF and ELF.
2978 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2980 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2981 (OBJ_PROCESS_STAB): Don't define.

2985 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2986 the type of symbol set symbols which happen to be in the absolute
2987 or undefined section.

2991 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2992 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2993 and -many (all architectures).
2995 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2997 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2998 involving a function symbol which is not a plabel to zero.
2999 (md_apply_fix): Never pass a function symbol to field_adjust.
3001 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3003 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
3004 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
3006 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
3007 branch with an instruction that uses $at, in case the branch is
3009 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
3010 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
3011 to make it pcrel_offset.
3012 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
3013 reloc->address; another gruesome hack to get gas reloc handling to
3016 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3018 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
3021 (emit_insn): New function.
3022 (md_assemble): Call it.
3023 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
3025 (lituse_pending): New variable. Set by anything that generates a
3026 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
3027 tested by code that might want to emit a LITUSE reloc.
3028 (emit_unaligned_io): New function. Currently calls md_assemble,
3029 but it should eventually be converted to generate the insn itself
3030 and call emit_insn directly.
3031 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
3032 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
3033 emit_bis_r): Likewise.
3034 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
3035 (alpha_ip, label get_macro): Don't emit the final instruction if
3037 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
3038 unaligned memory access macros.
3039 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
3040 the value can't be resolved.
3042 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3044 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
3045 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
3046 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
3048 (mips_force_relocation): New function.
3049 (md_apply_fix): Set fixP->fx_done appropriately.
3050 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

3058 * config/tc-mips.c (enum mips_pic_level): New enum.
3059 (mips_pic): Change from int to enum mips_pic_level. Change all
3060 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
3061 (load_address): Handle EMBEDDED_PIC.
3062 (macro): Handle EMBEDDED_PIC in all PIC cases.
3063 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
3064 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
3065 -non_shared to use NO_PIC (this is how the Irix 5 assembler
3066 works). Do not permit -G with SVR4_PIC.
3067 (s_abicalls): Warn if -G was used, and force -G 0.
3068 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
3069 anything but a.out, not just for ELF. For ECOFF, don't generate a
3070 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
3072 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
3074 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3076 * config/tc-hppa.c (create_new_space): Use ints, not chars as
3077 parameters to avoid losing when compiling with HP CC.
3078 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
3080 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
3082 * Makefile.in (config-stamp): If `defs' is defined, emit a
3083 preprocessor directive to create a macro named by this value into
3084 config.new; don't explicitly go for BFD_ASSEMBLER.
3085 * configure.in: Define `defs', not `BFDDEF'. Set it to
3086 MANY_SEGMENTS for any obj-coffbfd target.
3087 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
3088 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
3090 (LOCAL_LOADLIBES): Deleted.
3091 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
3092 * config/m88kcoff.mt (TDEFINES): Ditto.
3093 * config/ebmon29k.mt: Deleted.
3094 * config/h8300hds.mt: Deleted.

3096 * config/sparc.mt: Deleted.
3097 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

3099 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
3100 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

3118 bfd_set_symtab is called.
3119 (dump_section_relocs): Note whether a symbol is a section symbol
3121 (adjust_reloc_syms): For now, always supply an absolute symbol for
3122 fixups without symbols but not yet `done'. Use section_symbol to
3123 get the symbol, instead of going directly for abs_symbol.
3124 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
3125 reloc is not a section symbol and is not in the symbol table.
3126 (set_symtab): New function, broken out from write_object_file.
3127 Counts symbol table instead of relying on an earlier count.
3128 (write_object_file): Call set_symtab, but do it after potentially
3129 invoking the *_frob_file macros. Don't bother counting symbols.
3130 Call symbol_remove, instead of expanding it in place. Moved the
3131 conditionalized `object_file_size' declaration down to
3132 conditionalized block where it's used. When using the absolute
3133 symbol for a fixup without a symbol, set sy_used_in_reloc.
3134 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
3135 the correct symbol for the absolute section.
3137 * subsegs.c (section_symbol): Use symbol_new instead of
3138 symbol_make, since we may want it to go into the symbol table.
3139 Make the new symbol have internal linkage. If
3140 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
3141 symbol with the newly created GAS symbol.
3142 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
3143 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

3148 (in_signed_range): New function.
3150 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
3151 (sparc_ip, label "immediate"): Reject constants for pcrel
3152 instructions only if the relocation type indicates a "call"
3153 instruction and the offset is within range of a "jmpl %g0". If
3154 it's not in range, use the absolute section symbol plus an offset.
3155 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
3157 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
3159 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
3162 * configure.in: Eliminated all targets using obj-coff but not
3163 defining BFD_ASSEMBLER; I think all such targets that are
3164 supported will be matched by real CPU-OS combinations earlier in
3166 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
3167 some comments about the dpx2 configuration, but left it disabled,
3168 since it couldn't be reached before.
3169 (target a29k-amd-ebmonold): Deleted.
3171 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

3179 the 'j' operand if there are no further alternatives for this
3182 * config/obj-coffbfd.c (adjust_stab_section): Initialize
3183 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
3184 is not SEG_UNKNOWN rather than checking whether it is >= 0.
3186 * config/tc-mips.c (mips_align): Take new argument, label, and use
3187 it instead of global insn_label.
3188 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
3189 call to mips_emit_delay and pass it to mips_align.
3191 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3193 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
3195 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
3196 argument to a .callinfo directive. Don't loop forever on errors.
3198 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
3199 use pre-defined registers as arguments.

3203 * write.c (write_object_file): Check both S_IS_LOCAL and
3204 S_IS_EXTERNAL when deciding whether to discard a symbol.
3206 * config-gas.com: Scan Makefile.in, not version.c, for current
3207 version number. Delete all versions of temp files when finished
3208 with them. Create config.h.

3211 values to reduce number of lookups with S_GET_VALUE. Skip debug
3212 symbols to avoid "a really nasty bug". (From Holger Teutsch,
3213 holger@botbso.rhein-main.de.)
3214 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
3215 field. (Also from Holger Teutsch.) Watch for a would-be register
3216 mask that spans frags.
3218 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
3219 this_base, not line_base. (Patch from Andreas Arens,
3220 ari@obelix.av.rwth-aachen.de.)
3222 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
3223 look local if they're exported or undefined. Used to be done for
3226 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
3227 Get it from the looked-up symbol, instead of using the string from
3228 the input stream, which is no longer null-terminated.
3229 (LEX_PCT): New macro, defaults to 0.
3230 (lex_type): Use it for `%'.
3232 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
3233 (vip_op): Now static, and returns void. Callers changed. Added
3235 (vip): Ditto. Call as_fatal directly if a program bug is

4867 Delete dead code. Simplify.
4868 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
4869 applied are in range. Use bfd_put_32 rather than inserting each

4948 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4949 standard hpux include files to pick up various function decls.
4951 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4965 descriptor information to the BFD symbol.
4966 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

4984 of interest to the linker. ENTRY/EXIT relocations for SOM are
4985 an example of marker relocations.
4986 * write.c (write_relocs): Instead of assuming size of a relocation
4987 is 4 bytes, pick up the size from relocation itself.

5017 pass new argument for i, j and o cases.
5018 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

5239 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
5240 the table, require that the one without bit 0x1000000 set come
5241 first. Require further that it be case 'b' or 'P'. The a29k
5242 opcode table already meets these constraints.
5243 (machine_ip): When handling case 'i' or 'A', make sure that the
5244 appropriate opcode really exists by looking at the next entry in

5299 * write.c (write_relocs): For relocs that are pc_relative and
5300 pcrel_offset and not partial_inplace, adjust reloc->addend to

5351 OPTIONAL_REGISTER_PREFIX if either is already defined.
5353 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
5355 * configure.in: Set bfd_gas for all sparc targets. Added facility
5356 for keeping or rejecting configurations still under development;
5357 default is to assume production environment, and reject configs
5358 still being worked on. Mark Elf configurations (except sparc and
5359 i386) as developmental. Deleted cases matching some generic names
5360 in favor of more specific names. (E.g., when we get Alpha

5377 through inclusion of tc-hppa.h. Delete all forward declarations
5378 for functions only used within tc-hppa.c, likewise for structures,
5379 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
5380 conditional code in a few small places.
5382 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
5383 structures, global variables, forward declarations together.

5385 conditional code -- try to group conditional code together
5386 into a few places. Make all functions and variables which
5387 are only used within tc-hppa.c static. PARAMize all functions.
5388 Add comments to functions. Delete unused functions, variables,
5389 #defines, etc. Delete unused members within structures. Delete
5390 ldil;ble hacks -- it is believed they were installed to work
5391 around old gas bugs. Avoid using mixed case for local
5392 functions, variables, and structures. Fix formatting problems
5393 not found by GNU-indent. Add FIXME notices for things which
5394 should be worked on the near future. Delete lots of old
5395 useless (1.36 PA-SOM) code.
5397 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
5398 field of the fixS structure. Needed to build unwind

5424 a multiple of the section alignment rather than always a
5427 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
5428 bits are zero (eg they specify no relocations), then do not even
5429 bother adding their entries to thesymextn section.

5474 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
5476 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
5477 ELF, since the ELF object format does not have these type of
5478 relocations. Change the abort into as as_bad and return
5479 BFD_RELOC_NONE to silence compiler warnings.
5480 (md_assemble): Keep track of the instruction size. Allow white
5481 space between the $ and the constant for compatibility with older
5482 gases and other assemblers.

6506 * expr.c (expr): Don't let absolute_section override
6507 undefined_section for the return value.
6509 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
6510 pseudo-op with a poc_handler field of NULL, ignore it and treat it
6511 as an instruction instead.
6512 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
6515 * config/tc-h8500.c (md_begin): Use a local variable when
6516 initializing md_relax_table to avoid warnings about modifying a

6527 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
6528 case to set obj_format=elf. Must go before i386-*-sysv* case that
6529 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
6530 *-*-solaris case, and move to before *-sysv* case that wants to
6531 set obj_format to coff.

6557 * Extensive changes to permit symbols to contain any expression
6558 type and to delay the computation of the expression until the
6559 value is actually needed. This permits setting symbols to values
6560 calculated based on object code size. Expressions were changed to
6561 no longer be in a section, to stop the overloading of segment and
6562 expression type that previously occurred.
6564 * as.c (big_section, pass1_section, diff_section, absent_section):
6566 (expr_section): Added (used for dummy symbols which hold

6650 (previous_section, previous_subsection): New vars.
6651 (obj_elf_section): Save current place in case DWARF code wants us
6652 to pop back to it. Handle unquoted section name as well as quoted
6653 section name. Don't crash on invalid strings.
6654 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
6657 * config/obj-elf.h: Don't include struc-symbol.h.

6766 sy_resolved and sy_resolving single bit fields.
6767 * symbols.c (symbol_new): Don't initialize sy_forward field.

7968 lines; I don't think that can be done portably.
7969 * config/tc-mips.c (macro): Use $AT if target register is zero in
7970 load instruction, which it can be for a floating point load.

8044 prototypes for all static functions. Moved existing minimal
8045 debugging format support info #ifndef OBJ_ECOFF blocks.

8094 * make-gas.com: Find obstack.obj if it's not in the current
8096 * read.c (s_ignore): Don't declare is_end_of_line. It's
8097 redundant, and triggers a VMS gcc compiler bug.
8099 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
8100 current segment as an argument. (Ignored in all cases but VMS.)
8101 All callers and definitions changed.

8125 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
8128 * configure.in: mips-bsd configuration was missing format spec.
8131 * Makefile.in (Makefile): Depends on configure.in.
8133 * config/tc-mips.c (append_insn): Don't check for alignment of
8134 frag in memory; alignment of instructions in section is a separate

8154 * config/tc-sparc.c (s_xword): Now call big_cons, so large
8155 constants are accepted, but symbolic values are not. GCC will not
8156 generate the latter currently.
8158 * frags.c (frag_init): New function.
8159 (zero_address_frag, bss_address_frag): Now initialized at run
8161 * as.c (main): Call frag_init.

8416 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
8418 * configure.in: recognise all sparclite variants
8420 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8422 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
8423 accidentally changed to use subseg_change where it should have
8426 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
8428 * expr.c (operand): If character other than comma or newline is a
8429 logical end-of-line character, use the newline case.
8430 From Eric Youngdale:
8431 (operand): Set X_add_number field for floating-point numbers.
8432 (operand): Treat zero byte as end-of-operand.
8434 * configure.in (per-target): Look for with_bfd_assembler option.
8435 For now, only accept "no", until the merge is done.
8437 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
8438 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
8439 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
8440 * read.c: Finish conversion to S_* macros in the VMS only
8441 parts of the program. Add "const" modifier to hex_value.
8442 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
8444 * expr.c: Add "const" modifier to hex_value.
8445 * symbols.c: Finish conversion to S_* macros in the VMS only
8446 parts of the program. Add "const" modifier to
8447 md_[long,short]_jump_size. Remove declaration of const_flag
8448 (which will be declared in obj-vms.h).
8449 * write.c: Add "const" modifier to md_[long,short]_jump_size.
8450 Fix arguments to VMS_write_object_file.
8451 * config-gas.com: New file. Script for VMS systems to set up the
8452 configuration to build gas for VMS, and create config.status.
8453 * make-gas.com: Redone to work with new scheme.
8454 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
8456 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
8457 will swap bytes if needed on a big endian system. Use throughout
8459 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
8460 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
8461 types of malformed stabs. Change parsing algorithm so that we are
8462 more certain of having all of the information that we need on hand.
8463 * obj-vms.c (final_forward_reference): New function, used to help
8464 resolve the data types of as many struct elements as possible
8465 when some part of the struct is not fully defined by the compiler.
8466 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
8468 * obj-vms.c (VMS_write_object_file): Define all vtable psects
8469 as symbols as well in the object file. Look for external functions
8470 that start with "__vt.", and turn them into variables, since the
8471 g++ compiler is incapable of doing this.
8472 * tc-vax.c: Add '1' option for backward compatibility with older GCC
8474 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
8475 * input-scrub.c (as_where): Fix bug where as would crash if we did not
8476 have the name of the source file yet.
8477 * config/ho-vms.h: define HO_VMS, not HO_VAX.
8479 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
8481 * read.c (s_data): Always use "data_section", since it'll map to
8482 SEG_DATA or SEG_E1 if needed.
8483 (s_lcomm): Likewise with bss_section.
8484 (s_fill): Use memset, not bzero.
8486 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
8488 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

8502 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
8503 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

8507 (section_alignment): Declare only if not BFD_ASSEMBLER.
8508 (big_section, reg_section, pass1_section, diff_section,
8509 absent_section, text_section, data_section, bss_section): If
8510 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
8511 mapping to segT enum values.
8512 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
8513 if these are used or defined, if BFD_ASSEMBLER.
8514 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
8515 subseg_new split into two functions.
8516 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
8518 * as.h (volatile): Don't define if already defined.
8519 (had_errors, had_warnings): Provide prototypes for ANSI C even if
8521 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
8522 declare with format attribute for -Wformat checking.
8524 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
8526 * app.c, config/tc-*.c: Don't include read.h, since it is already
8529 * These are based on patches from Minh Tran-le
8530 <mtranle@paris.intellicorp.com>.
8531 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
8532 obj_format coffbfd and gas_target i386coff for target.
8533 (i[34]86-*-isc*): New host (uses sysv).
8534 * config/i386aix.mt: Removed (no longer used).
8535 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
8537 (LDFLAGS): Added, defined as -shlib.
8538 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
8539 * config/te-sco386.h (LOCAL_LABEL): Don't define.
8540 (DOT_LABEL_PREFIX): Define.
8541 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
8542 name rather than L0\001.
8543 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
8545 * symbols.c, symbols.h (local_bss_counter): Removed.
8546 * write.c (write_object_file): bss no longer uses
8547 local_bss_counter. Pass correct data and bss size to
8548 VMS_write_object_file.

8554 (size_section): Restored sanity check.
8555 (do_relocs_for): Base section address on s_paddr rather than
8556 computing it. Adjust a29k R_IHIHALF special case to account for
8557 section paddr (used to require paddr to be zero). If there are no
8558 reclos, set s_relptr to 0. Set relocation size in object_headers.
8559 (fill_section): Always set s_vaddr here, removing
8560 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
8561 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
8562 Set STYP_INFO for .comment.
8563 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
8564 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

8566 H_{SET,GET}_* macros.
8567 (do_linenos_for): Set lineno size in object_headers.
8568 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
8569 set s_vaddr here. If string_byte_count remains 4, set it back to
8570 0, and only write strings out if there are some. Call
8571 fill_section before do_relocs_for and do_linenos_for.
8572 (obj_coff_section): Handle optional quoted second argument giving
8573 section characteristics.
8574 (obj_coff_bss): Added to handle .bss.
8575 (obj_coff_ident): Added to handle .ident (puts string in .comment

8578 (fixup_mdeps): Change to segment. Call frag_wane after
8580 (fixup_segment): Explicitly check S_IS_COMMON before making 386
8581 adjustment (already happened only for common symbols, but this is
8583 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
8584 * config/tc-i386.c (s_bss): Don't use if I386COFF.

8595 (do_scrub_next_char): For \", return " not '.
8596 (symbol_chars): Now const.
8598 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
8599 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
8601 * config/obj-coff.h: Don't use #elif.
8603 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
8604 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

8630 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
8631 using ZERO_BASED_SEGMENTS.
8632 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
8633 never set segment address for SEG_E2 (.bss) and don't write out
8634 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
8635 (obj_coff_endef): Don't merge labels or symbols awaiting forward
8636 definitions, and don't merge tags with non-tags. Check for .bf
8637 rather than just checking whether the second character is b and
8638 the third character is f.
8639 (obj_coff_val): gcc can generate values which we don't handle
8640 correctly; discard information for now, since it only affects the
8641 debugging information.
8642 (tag_find_or_name): Don't insert tags in the symbol table.
8643 (yank_symbols): Don't merge labels.
8644 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

8887 support for C source listings. (obj_coff_endef): look in the right
8888 part of the symbol for the symbol name
8890 * tc-m68k.c (get_num): make it work for all segments, not just the
8893 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
8895 * configure.in: recognize i386-*-bsd emulation.

8904 * tc-z8k.c: lots of bug fixes
8906 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8908 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8909 #elif, since it is not supported by old compilers.
8910 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8911 couple of expressions in tc-m68k.c.
8913 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8915 * read.c (cons): If NO_RELOC is defined, use it.
8917 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8919 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8921 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8922 local labels to start with a .) and set REGISTER_PREFIX to %.
8923 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
8925 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

8939 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
8941 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8942 sections starting from zero, rather than making them consecutive.
8943 This makes subsequent reloc calculations easier, esp if the object
8944 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8945 allocate lcomm in .data rather than in .bss. It seems that some
8946 tools can't cope with a non-zero sized bss before linkage.
8948 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8950 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8954 "-mno-688[58]1" options.
8956 * tc-m68k.c: Added CPU32 support.

8969 * Makefile.in (install): if $(tooldir) exists, install as in
8972 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8974 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8975 .word is < -32768 or > 32767. The -J flag causes the error to be
8976 ignored. This is to catch over-sized switches generated by gcc on
8977 systems which don't support the broken .word hack.
8978 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8979 write.c (fixup_segment): check for signed .word overflow if
8980 WARN_SIGNED_OVERFLOW_WORD.
8982 * write.c (fixup_segment): fixed missing parens in expression
8983 checking for byte or word overflow.

8999 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
9001 * input-scrub.c (input_scrub_push): call input_file_begin, not
9003 messages.c (as_perror): print ": " between the passed in error and
9004 the strerror, like perror does.
9006 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

9009 From Steve Chamberlain:
9010 Makefile.in: Handle m68*-*-coff*.
9011 read.c, read.h: add mult argument to s_space
9013 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
9014 Motorola and MIT syntax; gas can now assemble either type of
9016 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

9022 (write_object_file) call fixup_mdeps
9023 (fixup_segment) set fx_subsy to 0.
9024 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
9026 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
9029 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9031 * Makefile.in (LIBS): Include opcode library.

9056 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
9058 * config/tc-m68k.c (init_table): Now const. Always include 68851
9059 data, so that "bc" is available to 68040 cache instructions.
9060 Added "tt0", "tt1", and 68ec030 variants.
9061 (md_assemble): Complain if 68000 (only) and 68881 are specified.
9062 (enum _register): Added TT0, TT1.
9063 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
9064 line number correctly in "internal error" messages. Don't print
9065 architecture-mismatch message for operand errors.
9067 From Colin Smith (colin@wrs.com):
9068 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

9090 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
9091 has already been formatted (but may still contain %-characters).
9094 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
9096 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
9097 written with indirection on the last two operands, which can be
9098 either data or address registers. Added a new operand type 'r'
9099 which accepts either register type. Added '(' to notend stuff in
9100 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

9378 * flonum-const.c: renamed flonum-konst.c to stop dos name
9381 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
9383 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
9384 tc-m68k.h to te-sun3.h.
9386 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
9388 * configure.in: vxworks68 gets te-sun3.h.
9390 * expr.c: remove limitation that local_labels_dollar or
9391 local_labels_fb must be < 10.
9393 * symbols.c: remove local_labels_dollar, replace with a function
9394 interface for a sparse array. All users adjusted.
9396 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
9398 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9400 * doc/Makefile.in: commented out line for building as-all.texinfo.
9403 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
9405 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
9407 * Makefile.in: added check target.
9409 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9411 * Makefile.in: added tooldir and program_prefix.
9413 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
9415 * write.{c,h} (fix_new): Make these declarations consistent.
9417 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
9419 * Makefile.in (strerror.o): Add rule so that broken Sun make can
9422 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
9424 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
9426 * expr.c (operand): if can't work out what sort of operand it is,
9427 then look through FLT_CHARS for a hint.
9429 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
9431 * Makefile.in, configure.in: removed traces of namesubdir,
9432 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9433 copyrights to '92, changed some from Cygnus to FSF.
9435 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
9436 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
9437 copyrights to '92, changed some from Cygnus to FSF.
9439 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9441 * expr.c: If an expression is single comma, then return with
9442 SEG_ABSENT rather than an error - since the sparc front end does
9443 really strange things with things like fbge,a
9445 * as.h: include bfd.h if using many sections
9446 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
9447 local labels didn't work.
9448 * listing.c (list_symbol_table): don't core dump when there's no
9450 * write.c, write.h: call fix_new with the right number of args on
9452 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
9455 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
9457 * app.c: MRI compatibility - allow single quote to start a string.
9458 * as.c: fix typo recently introduced.
9459 * as.h : Don't include aout/reloc.h - it's not right for COFF!
9460 * expr.c: Much rewriting, to accomodate MRI syntax for
9461 expressions. Also easier to read now.
9462 * listing.c: Put back defuns
9463 * read.c: modified to accept MRI syntax, put back listing pseudo
9464 ops so that an assembler built with NO_LISTING ignores list ops
9466 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
9467 machine is a SPARC or a 29K.
9468 * config/obj-aout.c: added s_sect pseudo op
9469 * config/obj-coffbfd.c: lints, set the filehdr flags right and
9470 fill in the timestamp.
9471 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
9472 anymore, define all the relocs which the tc-<x> bit will use so we
9473 can translate from them to the coff types.
9474 * config/tc-a29k.c: reloc_type isn't ane enum any more
9475 * config/tc-m68k.c: Added NO_RELOC definition.
9477 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
9479 * Makefile.in: put header files before C source for TAGS; remove
9480 references to non-existent syscalls.h.
9482 * read.c, write.c subsegs.c: back out the .bss changes.
9484 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
9486 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
9490 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
9492 * symbols.c (local_label_name): symbols now start with ^A.
9494 * read.c, subsegs.c, write.c obj-coff.c: added handling of
9495 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
9496 generate these sections. .align: will use NOP_OPCODE or 0
9497 for padding. This is just for being nice to the
9500 * expr.c (operand): changed to generate local label "\001L0"
9501 starting with a ^A so that it is recognized as a local label.
9503 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
9505 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
9506 i/o opcodes - inb, inw, outb and outw. string manipulation with
9507 att syntax - scmp, slod, smov, ssca, ssto.
9509 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
9510 to just after .file .
9512 In obj_crawl_symbol_chain() where it tries to put the external
9513 symbols apart, with the condition:
9514 (!S_IS_DEFINED(symbolP) &&
9515 !S_IS_DEBUG(symbolP) &&
9516 !SF_GET_STATICS(symbolP))
9517 it was moving too many symbols out. So I switch it back to the
9519 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
9521 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
9522 so that we don't use the F_RELFLG which make the linker complain
9523 that somebody has stripped the relocation info.
9525 Also, the AIX ld program require that the relocation table
9526 is sorted by r_vaddr like the standard ATT assembler does.
9528 [he also changed the sizeof(struct ...)'s into the coff
9529 style FOOSZ macros. I'm not sure this is right, but I can't
9530 remember why. xoxorich.]
9532 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
9534 * Makefile.in, configure.in, doc: use the doc. Build it, install
9537 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
9539 * read.c: white space and comments only.
9541 * configure.in: use the new atof-ns32.c for ns32k.
9543 * write.c: comment change only.
9545 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
9546 aren't yet integrated.
9548 * tc-i860.[hc]: blew off the dust. Something must still be done
9549 about conflicting relocation types.
9551 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
9554 * tc-i960.c, tc-sparc.c: white space and comments only.
9556 * tc-a29k.h: delete duplicate macro definition.
9558 * new file atof-ns32k.c copied from hack's last unreleased gas.
9560 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
9562 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
9565 * nearly everything. flush ChangeLog, package as gas-1.92.1.
9566 ChangeLog's prior to this are sketchy at best. I have logs.
9567 They just aren't ChangeLogs.
9574 version-control: never
